I've checked my console for errors, but I'm still unable to display it in the Material Data Table. I've been reviewing the code for some time now, but I can't seem to figure out what's wrong. The only thing that comes to mind is that the API may not be correct. The xxxxx stands for a URL of an API. Unfortunately, I cannot reveal the actual link.
